The Command Wolf (COMMAND WOLF) is a fictional weapon appearing in the *Zoids* franchise, developed and sold by TOMY (now Takara Tomy).

This entry also covers its various derivative machines.

The *Zoids* series features the Command Wolf from the first series (1983–1990), debuting in 1987. It also appears in the second series (1999–2006) across diorama stories, anime, manga, and other mixed media.

Command Wolf (COMMAND WOLF)

Armament (New)

Notable Pilots

During the Central Continent War, the Helic Republic—hard-pressed by the Zenebas Empire’s fast Zoid corps led by the Sabre Tiger—developed the wolf-type Zoid Command Wolf as a countermeasure. Known as the “Wolf of Mountain Warfare,” it was designed as a close-combat unit but excelled at pursuit and analysis, able to track enemies from the smallest clues, and was also used for independent reconnaissance missions. Its control display was the most advanced at the time, reducing pilot strain during operation.

Though it lacked the power of the contemporaneously developed Shield Liger, its maneuverability and ease of use earned the trust of pilots, functioning as a reliable support unit alongside the Shield Liger throughout the Central Continent War. By the Western Continent War, with few Republic Zoids able to match Imperial counterparts in its class, the Command Wolf became the backbone of the Republic’s high-speed units.

*(Old = Central Continent War / 1st Series, New = 2nd Intercontinental War / 2nd Series)*

• Twin Beam Gun Turret (Old) / 50mm Anti-Zoid Twin Beam Gun Turret (New)

Mounted on the back. The turret can detach and operate independently as a recon vehicle, and also provide aerial fire support.

• Smoke Dischargers (Old/New)

Waist-mounted. Launch smoke to confuse the enemy. Also doubles as an acceleration booster.

• Electro-Magnetic Fangs (Old) / Electron Bite Fangs (New)

Mounted in the jaws. Generates electromagnetic waves, delivering devastating close-range attacks. Suited for striking enemy weak points.

• Strike Claws (New)

The claws on all four limbs, which can be electrically charged for attack.

The Command Wolf was based on wolf-type Zoids long used by the Wind Tribe of the Central Continent.

Originally domesticated for hunting, generations of selective breeding enhanced their intelligence, allowing them to understand human commands. During the tribal war era, they were used in transport, defense, and even sport. Around ZAC 1960, they were mechanized—replacing most of their bodies with artificial components—and by ZAC 2042, the Command Wolf rolled out.

Even in the 2nd Intercontinental War, wolf-types remained valuable thanks to their sheer numbers compared to Liger- or Tiger-types. However, Central Continent variants still could not overcome the superiority of the Lightning Saix.

Later, the Republic discovered larger wolf-type wild Zoids on the Western Continent, leading to the development of the König Wolf—a machine with power rivaling the Liger Zero.

Powered by a large wind-up Hi-Power Unit. It features a simple quadrupedal walking gimmick but no interlinked mechanisms. Manual gimmicks include opening/closing the cockpit canopy, lower jaw movement, head/neck/tail articulation, rotation and separation of the dorsal turret. A unique feature is the variable speed mechanism: lowering the head engages an eccentric ballast gear with the Hi-Power Unit’s forward gear, reducing walking speed through added load.

According to TakaraTomy internal documents, total sales reached 988,000 units across the 1st and 2nd series.

Zoids Battle Story (Shogakukan)* First appeared in *Zoids Battle Story 2*. Debuted during the defense of Hadrian Wall in ZAC 2042, where it entered alongside the Shield Liger and outmaneuvered infiltrating Hellcats, earning its first victory. In the battles of ZAC 2043, participated in a surprise attack on the Empire’s giant Zoid development facility. Accompanied the Shield Liger, attacked Dimetrodons en route, and successfully advanced to the base after refueling from a Salamander. However, the base self-destructed, and the giant Zoid (Death Saurer) under investigation escaped capture. In *Zoids Battle Story 3*, took part in combat in the Central Mountain Range during August ZAC 2045. Served effectively in both reconnaissance and combat roles.

Zoids Battle Story (Gakunen Edition)* In the Central Mountain Range battle, defeated by Sabre Tiger due to speed disadvantage, resulting in its destruction.

Zoids Official Fan Book (Shogakukan)* From August to October ZAC 2099, units belonging to the Republic Army’s Independent 2nd Fast Battalion participated in the assault on Mt. Olympus. Attacked by Saber Tigers en route, several Command Wolves were destroyed, but thanks to the Shield Liger’s efforts, they reached the summit and engaged the Death Saurer. The climactic battle ended in a massive explosion, wiping out nearly all Republic forces involved—only Lt. Tommy Paris, one of the Command Wolf pilots, survived.

Zoids -ZOIDS-* Deployed as a standard Republic unit, also operated by various characters including Irvine’s customized unit. In episode 49, a flashback shows Dan Flyheight (Van’s father) piloting one against three Imperial Corps divisions under Prozen, managing to force a draw with a glowing phenomenon from its fangs. Initially, both the manga *Chaotic Centuryand the anime planned to make Van’s first protagonist Zoid a Command Wolf, but TakaraTomy’s internal marketing shifted it to the Shield Liger instead.

Zoids New Century /ZERO* Featured with the Ballad specification machine.

Zoids Fuzors* Featured the Command Wolf AC piloted by Maskman.

Zoids Genesis* Featured the Command Wolf LC as part of the Digald Suppression Army’s forces.

Chaotic Century (manga)* Van’s father’s machine appears, nicknamed “Zeke.” In a past battle against a Wild Zoid, it used its ultimate attack “Ragnarök Fang” at the cost of its life, becoming dormant in Wind Colony. Later, when Raven attacked, the Organoid Zeke merged with the Command Wolf (Zeke) to reawaken it. Ultimately, it used “Ragnarök Fang” once more, completely destroying itself, but succeeded in taking Raven’s Saber Tiger down with it.

The Command Wolf, as a medium wind-up Zoid, appears in numerous video games, especially throughout the 2nd Zoids series.

Zoids 2: The Counterattack of Zenebas* Zoids -ZOIDS- Resurrection! ~Geno Breaker Chapter~* Appears as a medium-class Zoid. Includes four variations: standard, custom, and wild Zoids.

In *Republic vs Guylos Empire*, has a named variant “Command Wolf AT Equipment Type,” the personal machine of mercenary Ain. Zoids Saga Series / Zoids VS Series* Both series include standard and multiple custom variations throughout. In *Sagaand *Saga DS*, serves as the starter Zoid for Arcadia’s Three Beast Warriors. In *Saga DS*, appears as Prince Atley’s training machine. Zoids Infinity* Available as a selectable starting Zoid. Zoids Struggle / Zoids Full Metal Crash* Both feature the standard, Command Wolf Irvine Custom, and Command Wolf AC.

Customization includes Long Range Rifle, Assistance Booster, Long Range Cannon, and recolorable parts.

Profile A variation that appeared during the Central Continent War. Its coloration was changed to match assignment with the Republic’s MK-2 units. Alongside Bear Fighter NEW, it served as an escort to the Shield Liger Mark II.

In video games, it appears in the *Zoids VS. series* and *Zoids Tactics*.

Naming The designation “Command Wolf NEW” first appeared in the Zoids Official Fan Book. In some sources, it is also referred to as “Command Wolf New Type”.

Profile Appearing in both the *Zoids: Chaotic Century* anime and the *Zoids Battle Story*.

This was a damaged Command Wolf abandoned on the battlefield, recovered and independently customized by Irvine. Known as the “Black Wolf”. Due to the heavy use of non-standard parts during repair, some specs are inferior to the normal model, but responsiveness and reaction speed were improved. Equipped with a Long Range Rifle originally designed for the Gojulas, it could penetrate even the armor of large Zoids with a direct hit.

When it first appeared in the anime, it was equipped with the twin beam gun turret, later upgraded with a spread missile system, and from episode 16 onward carried the Long Range Rifle. It was said to become “ill-tempered” when Irvine piloted any Zoids other than this one.

Naming There are variations in naming conventions: “Command Wolf Irvine Custom”, “Command Wolf AS” in the *Zoids Battle Card Game*, “Command Wolf IS (Irvine Special)” in *Zoids Saga 2* and *Zoids Tactics*, and “Command Wolf IRVINE” in the *Zoids VS. series*.

Production Notes According to Tomy’s Yutaka Tajima, the color scheme for the Irvine Custom was devised by the anime staff. Since the color specification could not be recreated with the standard Command Wolf kit, the scheme was reproduced by painting the runners before assembly. The Long Range Rifle was designed by Hiroshi Miyata, who also designed the Hybrid Vulcans for King Gojulas and Dark Horn in the first Zoids series.

In the Battle Story During the Second Full-Scale War in July ZAC2100, Irvine’s Command Wolf fought as part of a mercenary unit of Attack Zoids. After engaging Imperial forces, it moved to intercept an Iron Kong PK base incursion. Ultimately, it was destroyed while shielding the Gojulas the Ogre.

In the Anime First appeared in episode 3 of *Zoids: Chaotic Century*. It accompanied Van’s Shield Liger (later Blade Liger) and Moonbay’s Gustav on their journey. At one point, it was equipped with spread missiles to counter Raven’s Saber Tiger.

In episode 47, Irvine ignored warnings and engaged the Geno Breaker alone, suffering fatal damage to the Zoid Core. Later, when the Imperial Army’s Lightning Saix prototype suffered a test accident and its memory bank was damaged, the Command Wolf’s memory bank was transplanted into it.

In the Manga In the *Zoids Battle Story* manga published in *Shogaku Ninensei*, Irvine’s machine appears similar to the anime. It fought against a counterfeit Irvine piloting a fake Irvine Custom Command Wolf (nicknamed “Guntine”).

In Games Appears in:

• *Zoids: Resurrection of the Dark God ~Genobreaker Chapter~*
• *Zoids Saga series*
• *Zoids VS. series*
• *Zoids Tactics*
• *Zoids Struggle*
• *Zoids Full Metal Crash*

In each of these titles, Irvine also appears as a character, and in *Resurrection of the Dark God*, *Saga*, and *Tactics*, his Command Wolf functions as his story-linked signature machine, consistent with his manga and anime portrayals.

Profile During the Western Continent War, following their victory at the First All-Out Battle, the Guylos Empire captured a large number of Command Wolves. These captured machines—totaling either 50 or 100 units—were repainted, had their IFF signals changed, and were incorporated into Imperial forces. Some were used as live-fire targets to analyze internal circuits and study armor weaknesses, while others were assigned to Imperial special forces and engaged Republic Command Wolf units in combat.

Data gathered from these captured Command Wolves would later be used in the development of the Lightning Saix.

In Games Appears in the *Zoids VS. series* and *Zoids Tactics* under the name Command Wolf EM, sharing the same coloring and backstory.

Profile Assigned to the Republic’s experimental ultra-high-speed combat unit, *Seven to Three*, composed of five newly trained ace pilots. Compared to standard Command Wolves, its power plant output has been increased by approximately 20%, giving it a maximum speed of 231 km/h.

During the Western Continent War, when a Republic Zoids unit encamped in the Red Rust Desert was ambushed by a Black Redler unit, the Blue Command Wolves appeared suddenly and are said to have saved them from crisis.

Profile Developed to adapt the Command Wolf for prolonged battles. This variant is equipped with the CP-04 *Attack Unit*, consisting of a Long-Range Cannon (also referred to as Twin Long-Range Beam Guns or Twin 250mm Long-Range Cannons) and boosters. The upgrades improve firepower while the boosters compensate for mobility. The later Command Wolf AC was a customized development of this AU type, adjusted to match pilot skill levels.

Naming The unit’s name appears with many variations across media:

• *Command Wolf AU* — Zoids Official Fan Book 2
• *Command Wolf Attack Type* — Zoids Official Fan Book 3
• *Command Wolf Artie* — CoroCoro Comic (June 2000 issue)
• *Command Wolf AT Equipment Type* — *ZOIDS2: Helic Republic VS Guylos Empire*
• *Command Wolf Attack Unit* — *ZOIDS SAGA*

Profile A Command Wolf variant armed with 250mm Long-Range Cannons to enhance firepower. The weight increase and reduced mobility are compensated by the use of assistance boosters. These units were deployed to the Republic Army’s Special Operations Division 416 (a raiding force composed exclusively of Command Wolf ACs, nicknamed the “Blue Army” due to their coloration). After the conclusion of the Western Continent War, both the unit and these Zoids were reassigned to the Lightning Division (Rayforce), where they supported the Liger Zero alongside the Shadow Fox. The AC primarily handled fire-support missions but also excelled at reconnaissance, using its superior detection capabilities to pinpoint enemy positions. Individual pilots often customized their ACs with slight variations.

Profile & Story Appears in the anime *Zoids: New Century /Slash Zero* as the personal unit of Ballad Hunter. Initially equipped with a long-range rifle, from episode 7 onward it was refitted into the Attack Custom. In episode 20, while pursuing Dr. Laon’s newly developed Shadow Fox of the Backdraft Group, it fell from a cliff and was destroyed by a missile strike.

The name “Command Wolf BlS” originates from the *Zoids Battle Card Game*. In contrast, the *Zoids Encyclopedia* uses the designation “Command Wolf AC”. When Kotobukiya released a model kit in December 2010 bundling both the long-range rifle and the Attack Custom, the

Appears in the anime *Zoids: Fuzors*. A new form of the Command Wolf created when the Command Wolf AC unisoned with the Blox Zoid Leo Striker. During unison, its coloring shifts from blue to gray, and the Leo Striker transforms into a weapons unit mounted on its back.

First appearing in episode 10, it is born when Sigma’s Leo Striker unisons with Maskman’s Command Wolf AC, which had been trapped in a scheme by their former comrade Marvis. With improved reaction speed and melee combat ability compared to its normal form, it allowed them to overcome the crisis and subsequently served as a new asset for Team Mach Storm. Its main weapon is the Zanbreaker, formerly Leo Striker’s tail. In its first unison, it demonstrated its special attack, the “Gaia Breaker,” in which the Zanbreaker’s blade extends to nearly double its normal length. In episode 17, it also deployed a yellow-green circular E-Shield.

Appears in *Zoids VS. III*, which is based on the *Zoids Fuzors* setting.

A custom Command Wolf equipped with a Long-Range Rifle. The large cannon reduces mobility, but if it hits, it possesses enough destructive power to take down even large-class Zoids in a single shot.

In the anime *Zoids Genesis*, it appears under the Digald Suppression Army. However, against the Bio-Zoids of the Digald Empire, weapons not made of Metal Zi are ineffective, rendering its prized Long-Range Rifle useless. Toward the end of the story, the supply of Metal Zi ammunition from the Soranohito allowed it to finally be effective against Bio-Zoids.

Appearing in the *HMM (High-End Master Model)* series as the “Command Wolf LC Zenebas Empire Specification”, this version was created as original lore for the model kit. It was described as a machine formally adopted by the Zenebas Empire, who, as a countermeasure against the Shield Liger units, procured or captured Command Wolves by any means available.

Because acquiring Republic-made parts was difficult, scavenging wreckage from downed enemy machines became common practice. For this reason, Republic forces nicknamed it the “Hyena Command”.

The primary pilot was Captain Wol Garrei of the Belna Kingdom Army, which had come under the control of the Zenebas Empire.

Appears in Zoids Generations. A clear Command Wolf with a black and red base color scheme.

Its first appearance was as a limited-release kit at the 21st Next Generation World Hobby Fair; the package at that time displayed the label of Mach Storm from Zoids Fuzors.

Command Striker Holotech A Unizon variation of Command Wolf Holotech and Leostriker Holotech.

A variation featured on the RHI-3 Command Wolf product package. Additional armaments included a high-speed cannon mounted under the body, small missile pods on the shoulders, and a close-combat beam gun on the tail. For forest warfare, this model prioritized enhanced armament over speed.

A variation featured on the RHI-3 Command Wolf product package. It was designed for long-range sniping at night, with the main cannon on its back replaced by a long-barreled cannon.

To reduce detection rates, an infrared control device was incorporated into the engine exhaust port.
